I think this principle of always using the simplest regex that does the job is a very good one. Remember, even if the regex works on all your test cases, there's a good chance someone in a year's time is going to come back to it and need to change it. Complex regexes are intrinsically very hard to debug, so it's a good idea to avoid them if you can.But is there any reason not to use a simpler regex? E.g., <xsl:analyze-string select="normalize-space($title)" regex="(.+) - (.+)"> In this particular case the simpler regex is also closer to the English-language description of the requirement: separate the content after the last "space dash space" The OP's regex fails to do this if, for example, the content after the last " - " includes a hyphen.
